Prolapse is a common anorectal disease, also known as rectal prolapse, which refers to the prolapse of the rectum of the anal canal outside the anus, and part of the prolapse is visible as a round, red, smooth surface swelling. For prolapse, many patients think that constipation, irregular bowel movements, anal swelling, congestion, and prolapse are prolapse, but in fact, similar symptoms can be seen in anal diseases such as anal papilloma, hemorrhoids, and intestinal polyps. So patients also need to be careful, what are the symptoms of prolapse? 1, prolapse: the main symptom of prolapse. In the early stage, the rectal mucosa prolapses during defecation and resets itself after defecation; with the development of the disease, the whole rectum or part of the sigmoid colon prolapses, even when coughing, weight-bearing or squatting, and it needs to be pushed back by hand or after resting in bed before it can be reset. 2.Bleeding: Generally no bleeding symptoms, occasionally when the stool is dry, there is blood dripping from the mucous membrane when rubbing, blood in stool or blood when swabbing with hand paper, the bleeding amount is small. 3.Moist: Some patients often have mucus overflowing from the anus due to the relaxation of the anal sphincter and weak contraction, resulting in a sense of moist. Or because of its prolapse and not reset in time, the rectal mucosa is congested, edematous or erosion, and the mucus stimulates the perianal skin and causes itching. 4.Pumping: Due to the mucosal subluxation, it causes rectal or colonic overturning, presses the anus, and produces a feeling of swelling, and some also feel paralysis in the femoral and lumbosacral areas. 5, embedded: when stool, anorectal prolapse failed to reset in time, a little longer, local venous reflux obstruction, thus inflammation and swelling, and lead to embedded. At this time, the mucosa gradually turns from red to dark red, and even superficial mucosal erosion and necrosis or strangulation and necrosis of the prolapsed intestinal segment due to contraction of the anal sphincter.
